摘要： Particulate water-soluble or water-swellable polymeric material is provided with a substantially uninterrupted continuous coating of crystalline material. Single particles or aggregates having a size below 1 mm in size can be made by mixing the polymeric particles with a substantially saturated or supersaturated aqueous solution of crystallizable material (optionally a melt of hydrate crystallizable material) and thereby depositing it as a continuous crystalline coating on the particles.

摘要： The invention provides a substantially dry particulate composition comprising a polyacrylamide and an amidase. An aqueous composition made by dispersing this into water will then have a satisfactorily low content of residual acrylamide even if the initial polymer was contaminated with monomer. The composition is made by blending dry polyacrylamide particles with the amidase.

摘要： A cross linked high molecular weight polymer formed from a water soluble monomer or blend of monomers and which has IV and/or solubility and/or rheology properties indicating that it would be unsuitable for use as a flocculant can be used as a flocculant after shearing the polymeric material. The shearing may be applied to the polymeric material before addition to the suspension that is to be flocculated or can be applied to the suspensionthat is being flocculated. The shearing increases the intrinsic viscosity of the polymeric material and can improve its rheology and solubility. The polymeric material must be of high molecular weight.

摘要： When flocculating an aqueous suspension of suspended solids using a high molecular weight synthetic polymeric flocculant, the shear stability of the flocs is increased if the polymeric material includes polymeric particles of below 10 .mu.m dry size. The flocculated solids can therefore be subjected to shear without increasing the amount of discrete suspended solids in the aqueous medium and generally they are subjected to shear by shearing the aqueous medium containing them, either before dewatering, generally on a centrifuge, piston press or belt press, or by continuously agitating them, for instance in a chemical reaction medium. The polymeric material is generally formed by mixing into water polymeric particles made by reverse phase or emulsion polymerization in the presence of added cross linking agent. Alternatively, particles insolubilized by insoluble monomer may be used. A reverse phase dispersion of water soluble polymer may be used if the particles remain undissolved, e.g. if they are added in the absence of an oil in water emulsifying agent.
摘要翻译：当使用高分子量合成聚合物絮凝剂絮凝悬浮固体的水性悬浮液时，如果聚合物材料包括低于10μm干燥尺寸的聚合物颗粒，则絮凝物的剪切稳定性增加。因此，絮凝的固体可以经受剪切而不增加水性介质中离散的悬浮固体的量，并且通常在脱水之前通常剪切含有它们的水性介质，通常在离心机，活塞压力机或带式压力机，或者通过连续搅拌它们，例如在化学反应介质中。聚合物材料通常通过在添加的交联剂的存在下混合成通过反相或乳液聚合制备的水聚合物颗粒来形成。或者，可以使用不溶性单体不溶的颗粒。如果颗粒保持不溶，则可以使用水溶性聚合物的反相分散体，例如，如果在没有水包油乳化剂的情况下加入。
